Lume not a good, crown guard even more flimsy >>>

but to be sure, you really need to open it up.
However, this may not tell all since it's easy to swap with a Unitas movement.

To be honest, I think that RXW Ken Trading watches will be discounted to the Russian version + $100 to $200. So, in total $300 to $400 if not box etc... If a box then maybe $500 to $600. Of course, this is just my opinion. The Russian versions also have a mineral crystal.

to be honest, I'm a buyer of an original RXW from Ken's trading with everything @ $700 tops.
